Abstract
The method for making fast food box by using starch as raw material includes the following steps: adding biogel in raw material starch, stirring and mixing, hot-pressing forming, cutting, spraying biogel, drying, checking and packing so as to obtain the invented product. The invented product is nice in appearance, low in cost, and can be biodegraded after use, also can be used as animal feed, free from environmental pollution.
Description
The present invention relates to a kind of preparation method of daily necessities one mess-tin.
Present mess-tin is plastic products mostly.Because a large amount of uses, the environmental pollution that causes is very serious.Eliminate this " white pollution " quite difficulty.As the pollution of polystyrene foam plastics lunch box, come the freon of self foaming agent on the one hand, bigger to atmospheric ozone layer influence; From discarded polystyrene, decomposed this plastics about 100 years on the other hand.People attempted again to replace plastic products (as patent 95207133.9) to reduce environmental pollution with paper products afterwards.But making this lunch box is to be raw material with paper, and pollute the early stage that papermaking causes, so neither completely safe plan.
For many years, we fundamentally solve problem of environmental pollution to the research of mess-tin, we select with starch is raw material, is aided with additives such as biogum, has been developed into all starch biodegradation fast food box (tool), promptly do not have pollute the early stage of papermaking, cost is lower than paper products, and can high-fallly separate.Be again good organic fertilizer after high-fall the separating, perhaps reclaim and make the animal feed with the back, but resource reutilization.
The objective of the invention is to propose a kind of disposable all starch biodegradation fast food box, simple for production, the work efficiency height, the discarded object after the use can not cause environmental pollution.
The object of the present invention is achieved like this, adds plant fiber powder in starch, or plant stalk powder (as corn straw powder), and biogum is after mixing reaction, hot-forming.Spray marine glue (separate case CN1087150A) immediately on production line, heat drying gets product.Its technology is: (Fig. 1)
Advantage of the present invention is that manufacture craft is simple, and cost is low, and product is attractive in appearance, practicality, with after can high-fallly separate, or make the animal feed, do not pollute the environment, and do not pollute early stage.
Embodiment 1: starch 75～80% (weight ratio, down together), plant fiber powder 10～20%, biogum 2～3%, blowing agent 0.5～1%, plasticizer 0.5～1%, mix and stirred 10～30 minutes, be metered in the mould, hot-forming, cut then, spray glue, drying, go-on-go, packing gets product.
Embodiment 2: starch 75～80% (weight ratio, down together), plant stalk powder 10～20%, biogum 2～3%, blowing agent 0.5～1%, plasticizer 0.5～1%, mix and stirred 10～30 minutes, be metered in the mould, hot-forming, cut then, spray glue, drying, go-on-go, packing gets product.
